To all 'whom-it may concern: I. l

Be it known that I, FURMAN M. KADLE, residing at Atlantic City, in the county of Atlantic and State of New Jersey, have invented new and 'useful Improvements in Draft Blowers, of

- This invention relates to a? blower or forced draft attachment for furnaces, heat# ing devices, or the like, and an object of the invention is to provide a. device which is applicable for attachment to any convening structure by means of which the forced draft creating device may be supported at. v door of the heater or the like.

the yrelatively arge inlet endof the body shell 1 so'that it will draw air inwardlyy through the open outer or inletvend 5, and force it at an increased rate of speedthrough the body shelll and outwardly through the outlet end 6v. In.use,`the outlet end 6 of the body shell'. 1 is inserted through the draft opening 7 -of a furnace, heater oranalogous devices 8 of any approved type, and the' air or draft from the body shell is directed upf wardly through thegrate 9 by means ofthe hinged door or closurev 10. The door or closure l0 is hingedly supported as shown at-A 1l at the lower lside of the body Shell l audit hasside flanges 12 thereon which fitv in the body shell. A flexible" adjusting strap 13 has one'end connected to the upper free end of the closure 10 in anysuitable manner, preferably by means of a. pin-14 which is inserted in the rolled edge 15 of the closure 10 and forms a pivotal or hinged connection of the body shell 1 and is guided by a suitf between' the .closure 10 and the strap 1,3. The strap 13 is slidable over theupper side orgrippin'g device 17 may be formed on the free endl of the strap 13.

It is, ot' course, to be understood, that the invention may be constructedA in various other manners and the parts associated in different relations and, therefore, I do not set 'forth in the claims hereunto appended.

`YVhat I claim is:

. 1. A draft creating device comprising a body shell, draft creating means therein, the outlet end ot' said shell adapted to be supported within a furnacedoor, a standard extending transversely through the inlet end of the body shell, and means co-operating with said standard and body shell for holding the inlet end of the body shell at adjusted elevations.

2. A draft creating' device comprising va body shell, draft creating means therein, a closure hingedat its bottom edge to the outer end of said body shell and having angled side edges,'and means for adjusting the positioniof said closure relative to said body of the draft.

3. A draft creating de vice comprising a 4. A draft creating device comprising a body shell, draft creating means therein, adjustable means for regulating' thedirection of the outward flow of the draft fromv said Y body shell, a supporting' standard extending through said body shell adjacent to its inlet end, and means co-operating' with said standard for supporting the body shell at adjusted elevations.

A draft creating device comprisinga body shell, draft creating means therein, adjustable means for regulating the direction of the outward How of the draft from said body shell, a supporting standard extending through said body shell adjacent to its inlet end, and means co-operating with said standard for 'supporting the body shell at adjusted eso-` elevations, a closure hingedly connected tov the body shell at the lower edge of its outlet end and adapted to be moved for regulating` the direction oftlow of air out of said body shell.
